The detent is set absolutely perfectly, for my tastes, to ensure a proper deployment, resulting in a consistent lockup every time. Titanium frame lock flipper knives are typically those that aim for an extremely smooth deployment. It works really well, and I never had any failed deployments in my time in carrying and using this knife. The flipper on the Arius blade, which protrudes out from the back of the handle, has a touch of jimping on it, just enough to give the index finger a spot of purchase when deploying. This blade is made to work, and look good while doing it. The edge put on the knife from the factory is quite small in appearance, usually alluding to a thin dimension behind the edge, once again aiding in cutting performance. Near the heel of the blade is a generous, yet subtle sharpening choil, to help the handle and blade from hitting the stone, should you choose to sharpen your own Arius. The field test section of the review will give more insight to this aspect of the knife, but in short, it cuts very well in just about any cutting medium. With a hollow grind on a blade, with one as tall as the Arius, cutting performance is maximized quite efficiently. Working down from the spine, and past the opening hole, begins the hollow grind. It’s edges are well chamfered, smooth, but with a perfect amount of purchase in use. The oblong opening hole makes for a great means of a secondary option in deployment, and somehow maintains the design queues of the knife as a whole. The blade has a large opening hole in it, along with a flipper tab. The spine also has a swedge that begins just after the thumb ramp on the blade, and continues out to the tip, giving yet another dimension of appeal to the aesthetic of the blade. The spine of the blade does not have any jimping to it, leaving a very clean look and feel to it. The saber portion of the blade maintains more of a lighter, machine ground stonewashed look, giving a nice contrast to the primary grind. The primary grind being hollow, has a nice satin finish to it, without leaving a hint of the machine ground lines to it. It’s difficult to describe such a blade in words alone, but we’ll give it a shot. The drop point blade shape comes in at a very capable 3.5”, and looks like James Bond in a piece of steel. Using the gold standard in today’s available stainless steel choices, the M390drop point blade is one that doesn’t disappoint.
